The Church of Saint John the Baptist in the Christian Quarter of Jerusalem is a small Greek Orthodox church. In its current form, most of the above-ground church dates to the 11th century, and the crypt to the Late Roman or Byzantine period (between ca. 324 and 500 CE). According to the Greek Orthodox tradition, the head of St. John the Baptist was held in this church.
The first structure, a north-south oriented trefoil building, was built sometime in the 4th-6th century and served for unknown purposes. It was damaged at the Persian conquest of Jerusalem in 614 and then extensively modified. A source can be interpreted to mean that it was restored during the 7th century by John the Almoner, Patriarch of Alexandria.
By the 11th century the ancient structure had sunk to at least 3 metres beneath the street level, with its doors and windows blocked, and served as a storage place for goods and water. During this century, an organisation of Amalfitan merchants settled in Jerusalem and acquired the south-west corner of the Hadrianic forum, where they established a pilgrim hospice, complete with a hospital and a church. The new church was erected above the ancient structure, which became its basement and dictated the tri-apsed layout of the entire church. This church was tended to by Benedictine monks. In 1099, Crusader knights injured during the siege of Jerusalem were treated at the hospital and after recovering started here what was to become the Order of Knights of the Hospital of Saint John of Jerusalem, named after the church, also known as the Knights Hospitaller. After the capture of Jerusalem by Saladin in 1187, the basement was apparently filled with debris.
At the end of the 15th century, the Greek Orthodox Patriarchate of Jerusalem acquired the church and most probably transformed the basement into a chapel, which according to excavator, Jean-Baptiste Humbert of the École Biblique, might well constitute the first time that the structure was used for a cultic purpose. During the 16th century the church was used for a short period as a mosque, but was soon recovered by the Greek Orthodox, who in 1660 build a large pilgrim hospice next to it. In the 19th century the crypt was cleared out, and an impressive reliquary was brought to light from the masonry of the altar.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
